Title: Semiconductor storage device
Inventor: HIDAKA HIDETO
IPC: G11C11/34
Filed: 1986-12-11
Abstract: PURPOSE:To prevent a read voltage difference from lowering to enlarge a read margin and to improve a soft error ratio by providing one or plural number of cross parts in respective pairs of bit lines in such a way that interbit capatity between pairs of bit lines adjacent to respective pairs of bit lines are equal. CONSTITUTION:Respective pairs of bit lines BL0, the inverse of BL0, BL and the inverse of BL1 are divided into four segments (a)-(d), and they cross at uniform points CP1-CP3. Namely, odd-numbered pairs of bit lines counted from the bit lines BL0 and BL0 the inverse of cross at the CP2, and even- numbered pairs of bit lines cross at the CP1 and the CP3. Since the capacity connection noise which respective pairs of bit lines receive from the adjacent pairs of bit lines at the time of signal reading are totally equal, the lowering of read voltage difference by the noise can totally be eliminated. Thus, the enlargement of the read margin and the improvement of the soft error ratio can be improved.

Title: Digital line fault control system
Inventor: FURUKAWA TAKASHI
IPC: H04M3/22
Filed: 1988-11-22
Abstract: PURPOSE:To attain maintenance management in matching with the fault state of a line by setting and revising a forward protection time, a backward protection time and a freeze backward protection time corresponding to a line. CONSTITUTION:When the fault is consecutive for the forward protection time of a line fault or above, a line control circuit 5b reports the production of a fault to a central processing unit 1 and the central processing unit 1 applies closing processing of the relevant line. When the line fault caused in a digital line 9 is restored and the normal state is consecutive for the backward protection time of the lien fault set in advance or above or the freeze backward protection time or above, a line control circuit 5b reports a fault recovery to the central processing unit 1. Then the restart instruction of scanning detection processing of a line signal is given to a line scanning detection circuit 5a. Thus, the forward protection time, backward protection time and freeze backward protection time of a line fault are easily revised by the station data revision. Thus, even if the occurrence state of the fault is changed due to the deteriorated line state, it is controlled accordingly.

Title: Coating method
Inventor: MIYAZAKI TAKASHI
IPC: G03C1/74
Filed: 1986-12-12
Abstract: PURPOSE:To permit stable coating by starting the coating at the spacing between the lip of a coating machine and web narrower than the intrinsic set spacing and returning the same to the intrinsic set spacing right after a bead is formed. CONSTITUTION:The coating is started at the spacing between the lip 6 of the coating machine and the web 9 narrower than the intrinsic set spacing and the spacing is returned to the intrinsic set spacing right after the formation of the bead. The web 9 travels by being wound around a back up roll 1 and contacts a coating liquid 8 passed on a sliding surface 5 from a slit 4 of the slide bead coating machine 2 in the lip part 6 of the coating machine. The bead 7 which is a ribbon-shaped liquid pool is formed in the lip part 6 and the coating liquid 8 is coated on the web 9 through said bead 7. The change rate of the bed spacing increases and there is the danger of inducing a coating trouble or nabbing of foreign matter on a base in the bead part and the consequent generation of a line trouble when the coating is continued while the narrow bead spacing is maintained. The spacing is, therefore, required to be returned to the intrinsic set spacing right after the bead formation. The continuous coating with which the coating lines at the top of the coating hardly arises is thereby permitted.

Title: Magnetic recording device
Inventor: HIGURE SEIJI
IPC: G11B5/02
Filed: 1986-12-15
Abstract: PURPOSE:To reduce a noise spectrum in a reproducing signal by recording a digital sound signal modulated by PSK system for each system of offset poly-phase PSK into the deep layer of a magnetic layer together with a high frequency bias signal. CONSTITUTION:Right/left channel analog sound signals incoming to terminals 31a, 31b is converted into a PCM sound signal by A/D converts 34a, 34b and given to an offset PSK modulator 36 via an encoder 35. The modulator 36 outputs a digital sound signal being the result of four-phase PSK modulation to the inputted digital sound signal. The resulting sound signal is subjected to band limit by a band-pass filter 37 and fed to a bias superimposition circuit 39, where the high frequency bias signal is superimposed thereupon. The superimposed signal outputted from the circuit 39 is subjected to a high frequency bias recording up to the depth of the magnetic layer of the magnetic tape 43 driven by sound rotary heads 41a, 41b to form a sound track. Thus, the reproduced noise spectrum caused by intermodulation distortion due to nonlinearity of the tape 43 is drastically reduced.
